Why does a leak in one unit reach the next?
Because water runs along shared cavities, ceilings and risers. A leak can travel several meters through the building before it appears in another unit.
Multi-unit buildings share framing, floor cavities, chases and risers, and water uses those spaces to move. A leak that starts in a bathroom can run down the wall cavity and into the ceiling of the unit below, and it can keep going along the riser. The stain may show in a unit that is not the source, and the source unit may look dry while the neighbor is wet. A response that checks only the source unit misses the damage it has caused elsewhere.
What does the owner or manager need from the response?
A written record of each unit, the readings, the materials removed, the photographs and the times the water was stopped and the drying started.
The owner or manager needs the record to deal with the building's insurer and with the residents. The record lists each unit separately and shows what was found and what was done, without deciding who is liable. The photographs and the readings are kept with the record, and the times are noted so the timeline can be shown. The response does not replace the building's own procedures for reporting a loss.
How is access handled in a building with tenants?
Access is arranged through the owner or manager, with notice to the resident where the tenancy requires it. The crew enters only with that arrangement in place, and the entry is recorded.
Residents have rights over their homes, and the crew respects them. The owner or manager is the person who arranges entry, and the notice and the time of each entry are recorded. If a resident is not at home, the arrangement is still made through the owner or manager. The crew does not enter a unit to which it has not been given access, and it explains to the residents what is being done and why it takes the time it does.
Does the response decide who pays?
No. The response records the damage and the cause. Liability and the payment of the work are for the owner, the manager, the residents and the insurers to settle.
The record is written to be used by the parties, and it does not take a side. A leak from a unit's own fixture, a shared riser and a neighbor's appliance can each be the cause, and the record shows what the readings and the photographs found. The homeowner or the owner should keep the record with the building's insurance papers and seek advice from the insurer or a lawyer on any question of liability.
Why is the first hour important in a multi-unit leak?
Because the water keeps travelling while the source runs, and every unit it reaches adds to the work. Stopping the source and checking the neighbors early keeps the spread smaller.
A leak in a building does not wait for the paperwork. Each minute the source runs, the water reaches another cavity or another unit, and the residents below may not know until the ceiling starts to sag. The first call should go to the owner or manager, and the source should be stopped at the unit valve or the riser valve. The line is answered 24/7 on (833) 490-5225, and the caller is asked which unit and which floor the water is on.
